Can-type heat exchanger

Abstract

A can-type heat exchanger may include a housing having a space therein, integrally formed with a mounting portion, and a first inlet and a first outlet; a partition wall integrally formed to the housing, separating the space and the inside of the mounting portion, and forming a bypass passageway inside of the housing; a heat radiating unit inserted into the space, provided with connecting lines alternately formed by stacking a plurality of plates; a cover cap mounted at opened one surface of the housing, and a second inlet and a second outlet for communicating a second connecting line of the connecting lines; and a valve unit mounted at the first inlet formed in the mounting portion and penetrating the partition wall in the mounting portion, selectively opening and closing the space or the bypass passageway separated by the partition wall using linear displacement.

AI Technical Summary

Benefits of technology

The patent text describes a valve unit that can control the temperature of operating fluids based on the vehicle condition, using a can-type heat exchanger that can improve heat exchange efficiency, reduce weight and size, and simplify engine layout. The valve unit can selectively supply the operating fluids, eliminating the need for additional control valves and bifurcation circuits. The manufacturing cost is reduced, workability is improved, and the commercial value is increased. Additionally, if a defective heat radiating unit is produced before assembly, the valve responsiveness is improved, and hydraulic friction during cold starting is lowered, preventing slip and improving fuel economy and durability of the transmission.

Problems solved by technology

Therefore, constituent elements and assembling processes are increased and layout is complicated.

If additional bifurcation circuits and valves are not used, heat exchanging efficiency cannot be controlled according to a flow amount of the operating fluids.

Therefore, the temperature of the operating fluids cannot be controlled efficiently.

Further, additional valves for controlling flow of operating fluids should be mounted outside, thus constituent elements are complicated and weight and cost are increased.

Accordingly, when the heat exchanger is mounted in the engine compartment, layout is complicated and mounting space of the elements is not sufficient.
